The SharedSemanticMemoryLiteSettings class implements the settings for
the SharedSemanticMemoryLite module. The settings work by keeping its own
copy of a pattern recognizer so that the shared settings can be given to
multiple SharedSemanticMemoryLite modules that are in different models. The
copy is kept to ensure that the pattern recognizer behind the settings is
not modified after the shared settings are created.

clone

This makes public the clone method on the Object class and
removes the exception that it throws. Its default behavior is to
automatically create a clone of the exact type of object that the
clone is called on and to copy all primitives but to keep all references,
which means it is a shallow copy.
Extensions of this class may want to override this method (but call
super.clone() to implement a "smart copy". That is, to target
the most common use case for creating a copy of the object. Because of
the default behavior being a shallow copy, extending classes only need
to handle fields that need to have a deeper copy (or those that need to
be reset). Some of the methods in ObjectUtil may be helpful in
implementing a custom clone method.
Note: The contract of this method is that you must use
super.clone() as the basis for your implementation.
